Well, here are the new caps. I just redesigned them with thinner fins. They are available in aluminum or brass. They fit the 1.25 inch push in style necks. I am working on one for the newer HD models as well. check back and I'll be posting some more pics as they get finished.
I also have a few "blems". Ones that cast kind of funky, but that are just too cool to melt back down. I am selling them for 25% off regular price, so hit me up if you want one.
